The Educational Pipelinie For Women In Biology: No Longer Leaking?, Louise Luckenbill-Edds
The Educational Pipelinie For Women In Biology: No Longer Leaking?, Louise Luckenbill-Edds
ADVANCE Library Collection
Describing the past 30 years of progress toward gender equity in science, one observer wrote: "Although optimistic about future prospects, I must also point out some daunting toads and serpents lurking in the gardens of science. These challenge the rising generation of young scientists to be no less intrepid [that past activists who catalyzed change]" (Herschbach 1999, p. 66). The failure of the sciences to attract and retain women has meant a loss of diversity, as well as a loss of talent and creativity, that impoverishes research viewpoints and limits effective communication of science with diverse sectors of society.
Uncertainties In Sediment Quality Weight-Of-Evidence (Woe) Assessments, Graeme E. Batley, G. Allen Burton, Peter M. Chapman, Valery E. Forbes
Uncertainties In Sediment Quality Weight-Of-Evidence (Woe) Assessments, Graeme E. Batley, G. Allen Burton, Peter M. Chapman, Valery E. Forbes
Valery Forbes Publications
Uncertainties in sediment quality assessments are discussed in five categories: (1) sediment sampling, transport and storage; (2) sediment chemistry; (3) ecotoxicology; (4) benthic community structure; and (5) data uncertainties and QA/QC. Three major exposure routes are considered: whole sediments, and waters in sediment pores and at the sediment-water interface. If these uncertainties are not recognized and addressed in the assessment process, then erroneous conclusions may result. Recommendations are provided for addressing the identified uncertainties in each of the key areas. The purpose of this paper is to improve the reporting of sediment quality assessments.

Ethylene Synthesis And Sensitivity In Crop Plants, Stephen P. Klassen, Bruce Bugbee
Ethylene Synthesis And Sensitivity In Crop Plants, Stephen P. Klassen, Bruce Bugbee
NASA
Closed and semi-closed plant growth chambers have long been used in studies of plant and crop physiology. These studies include the measurement of photosynthesis and transpiration via photosynthetic gas exchange. Unfortunately, other gaseous products of plant metabolism can accumulate in these chambers and cause artifacts in the measurements. The most important of these gaseous by products is the plant hormone ethylene (C2H4). In spite of hundreds of manuscripts on ethylene, we still have a limited understanding of the synthesis rates throughout the plant life cycle. We also have a poor understanding of the sensitivity of intact, rapidly growing plants to …
Hibal: A Hydrologic-Isotopic-Balance Model For Application To Paleolake Systems, Larry Benson, Fred Paillet
Hibal: A Hydrologic-Isotopic-Balance Model For Application To Paleolake Systems, Larry Benson, Fred Paillet
United States Geological Survey: Staff Publications
A simple hydrologic-isotopic-balance (HIBAL) model for application to paleolake δ18O records is presented. Inputs to the model include discharge, on-lake precipitation, evaporation, and the δ18O values of these fluid fluxes. Monthly values of climatic parameters that govern the fractionation of 18O and 16O during evaporation have been extracted from historical data sets and held constant in the model. The ability of the model to simulate changes in the hydrologic balance and the δ18O evolution of the mixed layer has been demonstrated using measured data from Pyramid Lake, Nevada. Simulations of the response …
Determination And Consideration Of Flight Potential In A Laboratory Population Of True Armyworm (Lepidoptera: Noctuidae), Lizhi Luo, S. J. Johnson, A. M. Hammond, J. D. Lopez, J. P. Geaghan, K. R. Beerwinkle, J. K. Westbrook

Faculty Publications
Flight potential, a poorly understood phenomenon in the migratory true armyworm, Pseudaletia unipuncta (Haworth), was investigated in a laboratory population using tethered-flight techniques. True armyworm exhibited strong flight potential relative to other known migratory noctuids whose flight potentials were previously determined by similar techniques. Flight potential was generally low for 1-d-old moths and increased with age to day 5 of adult life. Flight speed and distance flown decreased for female moths from day 5 to day 10 as their reproductive system developed. The greatest average flight speed, total flight duration, and distance flown was exhibited by 5-d-old females and 10-d-old …

United States Geological Survey: Publications
Concerns about possible effects of lead-mining activities on the water quality of federally protected streams located in southeastern Missouri prompted a suite of multidisciplinary studies to be conducted by the U.S. Geological Survey. As part of this investigation, a series of biological studies were initiated in 2001 for streams in the current mining region and the prospecting area. In this report, results are examined for trace elements and other selected chemical measurements in sediment, surface water, and sediment interstitial (pore) water sampled between 2002 and 2005 in association with these biological studies. Compared to reference sites, fine sediments collected downstream …
Cancer Dose-Response Modeling Of Low Dose Radiation Exposure, Gizelle Susette Baker
Cancer Dose-Response Modeling Of Low Dose Radiation Exposure, Gizelle Susette Baker
MUSC Theses and Dissertations
Many late effects from exposure to ionizing radiation, including cancers, have been described in the literature. The identification and quantification of radiation-induced health effects is an important and complex issue. Recommendations for radiation safety and protection from the International Commission on Radiological Protection are made using a linear no threshold risk model on epidemiological data. A major obstacle in this process is the limited availability of data to directly measure the health effects of radiation on human populations. One way to circumvent this problem IS to use experimental data from laboratory animals and extrapolate across species to man. The cancer …
Reproductive Biology Of Smooth Cordgrass (Spartina Alterniflora), Xiaobing Fang
Reproductive Biology Of Smooth Cordgrass (Spartina Alterniflora), Xiaobing Fang
LSU Master's Theses
Smooth cordgrass (S. alterniflora) is a perennial grass that dominates the salt marsh in tidal wetlands along the Atlantic and Gulf Coast of North America and has been used for preventing soil erosion and restoring wetlands. Accessions collected from south Louisiana were studied to investigate flowering phenology, pollen viability, crossability, and seed production. S. alterniflora exhibited protogynous flowering where stigmas exserted 2 to 5 days from the floret prior to anthesis. Pollen shed primarily between 8:00 and 10:00 AM. Pollens were viable with average germination of 69% and stigma was receptive after exsertion. Pollen germinated in 15 minutes and pollen …

Fish Landmarks For Chromosome 11 Of Bombyx Mori: An In Situ Analysis, Charles Eugene Mcgovern
Open Access Dissertations
Fluorescence in situ hybridization (FISH) has been used to simultaneously identify the positions of the ribosomal DNA and the Sericin genes on chromosome 11 of Bombyx mori. The ribosomal DNA genes were detected using biotin labeled plasmid pBmR 161 and avidin-Texas Red and the Sericin 2 gene was detected using digoxigenin labeled plasmid 2002 and anti-digoxigenin-fluorescein. The position of the Sericin 1 gene was identified using the ribosomal DNA genes as a chromosomal landmark. Sericin 1 was detected using digoxigenin labeled bacterial artificial chromosome 9HJD and anti-digoxigenin-fluorescein. The chromosomal spreads were counterstained with diamindino-phenyl-indole (DAPI). The signals from the sericin …

Swallow-Worts, L. Tewksbury, R. Casagrande, A. Gassmann
United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications
There are three European species of swallow-worts found in North America: Vincetoxicum nigrum (L.) Moench (black swallow-wort), Vincetoxicum rossicum (Kleo.) Barb. (pale swallow-wort or dog strangling-vine), and Vincetoxicum hirundinaria Medik. (white swallow-wort) (Sheeley and Raynal, 1996). Swallow-worts are in the family Asclepiadaceae. Vincetoxicum nigrum and V. rossicum now are naturalized in northeastern North America, and both are invasive in natural areas and abandoned pastures (Lawlor, 2000). Swallow-worts are found in gardens and fields, along fencerows, roadways, grassy slopes, wooded edges, and streambanks. Tangled masses of swallow-wort vines shade and suppress native plants (Sheeley and Raynal, 1996). In Rhode Island, heavy …

Artificial Peptides Containing Ca,A- Disubstituted Amino Acids: Synthesis, Conformational Studies, And Application As Β-Strand Mimics, Yanwen Fu
LSU Doctoral Dissertations
Short peptides containing Cα,α-dipropylglycine (Dpg) at alternating sequence positions were synthesized and examined for conformational behavior. Peptide assembly was performed using Fmoc-solid-phase chemistry where the coupling with PyAOP could be significantly enhanced at elevated temperature. Circular dichroism (CD) and NMR conformational studies revealed that incorporation of Dpg residues induced folded structures into peptides. It was observed that Dpg residues adopted helical conformation in a helix-promoting sequence. The resulting helical structure was comprised of consecutive β-turns whose structure was stabilized by salt bridge in aqueous solution. In this study, the preparation of sterically and polyfunctional Cα,α-disubstituted amino …
The Influence Of Parenting Styles On Social Phobia In A College Sample, Kimberly Sue Fischer
The Influence Of Parenting Styles On Social Phobia In A College Sample, Kimberly Sue Fischer
Theses
Since researchers have only studied social phobia in the last several decades, the need to identify influencing variables is essential. While most researchers concur that familial factors have an impact on social phobia, the influence of family variables remain under investigation. Many studies have examined the impact of parenting characteristics on social phobia involving individuals in a clinical setting. However, few studies have focused on social phobia in a nonclinical setting with adults. This study explores the relationship between parenting styles of overprotection and rejection with social phobia in a college sample of adults. Subjects for this study were 35 …

The Effects Of Two Microbial Insecticides For Gypsy Moth Control On Carabidae Populations., Terry R. Carrington
Graduate Theses, Dissertations, and Problem Reports (ETD)
A study was conducted in the George Washington National Forest in Virginia and the Monongahela National Forest in West Virginia. Carabid samples were collected over four years and compared to soil characteristics, surface characteristics and meteorological conditions to determine what role these factors play in carabid habitat selection. Opportunity also existed to compare carabid populations before and after the application of microbial insecticides on the sampling sites. This study was conducted as as part of a larger project investigating non-target impacts from gypsy moth, Lymantria dispar (L.)(Lepidoptera: Lymantriidae), insecticide applications and the interaction of Entomophaga maimaiga Humber, Shimazu, and Soper …

Feasibility Study Of A Permanently Implanted Prosthetic Hand, Matt Williams
Feasibility Study Of A Permanently Implanted Prosthetic Hand, Matt Williams
Theses
The feasibility of a permanently implanted prosthetic hand was evaluated from both an internal biocompatibility and exterior mechanics point of view. A literature review of the issues involved in permanent implantation of a percutanious device was performed in the areas of bone interaction and fixation and neural interface control. A theoretical implant was designed for a 90th percentile male, using an HA-G-Ti composite material to provide a permanent base to which the hand could attach. Using a radial implant length of 1.87 inches and an ulna implant length of 1.32 inches, the simulated implant could withstand a push out force …
